Establishing a cluster
To successfully establish a cluster:
• Make sure UDP port 40000 is not used by any application. This port will be used by the cluster
management module for exchanging handshake packets.
• Perform the following tasks before establishing the cluster:
{ Specify a management VLAN. You cannot change the management VLAN after a cluster is
created.
{ Configure a private IP address pool on the management device for cluster member devices. This
address pool must not include IP addresses that are on the same subnet as the IP address
assigned to any VLAN interface on the management device or a cluster candidate device.
When a candidate device is added to the cluster, the management device assigns it a private
IP address for inter-cluster communication.
A cluster can be established manually or automatically. Using the automatic setup method:
1. You enter a name for the cluster you want to establish.
2. The system lists all candidate devices within your predefined hop count.
3. The system starts to add them to the cluster.
During this process, you can press Ctrl+C to stop the process. However, devices already added
into the cluster are not removed.
To manually establish a cluster:

Command Remarks
1. Enter system view.
system-view N/A
2. Specify the management
VLAN.
management-vlan vlan-id
Optional.
By default, VLAN 1 is the
management VLAN.
3. Enter cluster view.
cluster N/A
4. Configure the private IP
address range for member
devices.
ip-pool ip-address { mask |
mask-length }
By default, no private IP address
range is configured.
5. Establish a cluster.
• Manually establish a cluster:
build cluster-name
• Automatically establish a
cluster:
auto-build [ recover ]
Use either method.
By default, the device is not the
management device.
Enabling management VLAN autonegotiation
Management VLAN limits the cluster boundaries. To assign a device to a cluster, you must make sure the
port that directly connects the device to the management device or its cascade ports are in the
management VLAN.
Management VLAN autonegotiation enables a cluster management device to add ports directly
connected to it and cascades ports between cluster candidate devices to a management VLAN.
